Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

.DAY ONE...TODAY AND TONIGHT

...CHANCE OF THUNDERSTORMS ACROSS EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS THIS AFTERNOON...

A LARGE AREA OF SHOWERS AND THUNDERSTORMS WAS CONTINUING TO PROPAGATE
EASTWARD THROUGH MOST OF THE WESTERN HALF OF THE FORECAST AREA EARLY
THIS AFTERNOON. A SURFACE FRONT WAS LOCATED GENERALLY ALONG THE RED
RIVER WITH DEWPOINTS NEAR OR ABOVE 70 DEGREES IN THIS AREA. AN MCV
WHICH WAS SPAWNED FROM EARLY MORNING CONVECTION WAS PROPAGATING
EASTWARD GENERALLY ALONG THE RED RIVER AS WELL. INSTABILITY WAS
QUITE HIGH ACROSS THE EXTREME SOUTHERN PORTION OF THE FORECAST AREA
AHEAD OF THE MCV. THIS WILL CREATE THE POSSIBILITY THAT A STORM OR
TWO MAY REACH SEVERE LIMITS THIS AFTERNOON...MAINLY ACROSS THE
EXTREME SOUTHEASTERN PORTION OF THE FORECAST AREA.

FOUND IN THE CURRENT HAZARDS SECTION AT: WWW.SRH.NOAA.GOV/TULSA.

ISSUED AT YOUR LOCATION.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY
AN OVERNIGHT CONVECTIVE COMPLEX WILL AGAIN FORM ACROSS THE WESTERN
PLAINS SATURDAY NIGHT. WITH A MODERATELY UNSTABLE ATMOSPHERE ACROSS THE
AREA...OUTFLOW BOUNDARIES FROM THESE STORMS MAY PROVIDE THE FOCUS
FOR SHOWER AND THUNDERSTORM DEVELOPMENT SUNDAY. THERE WILL BE A
CONTINUED CHANCE FOR SHOWERS AND THUNDERSTORMS THROUGH THE FIRST
PART OF THE WORK WEEK AS A COLD FRONT MOVES INTO THE REGION FROM THE
NORTH.
